Drop DownMenu that displays usrnames in the database then shows selected user details

liamster75

I have made a connection between the drop down menu and the database which shows the current usernames in the rows. I then need to be able to click a box next to the menu that says go and then for it to redirect or refresh to a page with the selected usernames details. I have so far managed to get the selected user's name in the URL but i just need to know how to refresh the page and display a table or something with the users details?
